In Melbourne it had some not so great effects. A lot of people will use it instead of just walking a couple of blocks and the free zone is already the slowest and most congested part of the network, so it made PT worse for everyone else. As a resident of zone 1 I now get to subsidize the free users in the city and zone 2 because they removed zone 1 only tickets. I have a feeling the people complaining about the homeless would say the same things encountering "undesirables" on our PT though, it's just a disguised "I have to interact with poor people" argument.
